HAY-PRESS.

' To all whom it may concern Be it known that I, JOSEPH DAIN, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain'new and useful Improvements in Play-Presses, of which the following is a specification, reference being had to the accompanying drawings. I

Myinvention relates to hay presses, and particularly to presses of the type shown and described in my pending application, Serial No. 721,354, filed September 20, 1912, in which the plunger by which the hay is compressed is operated by an eccentricallymounted gear, or gears, rotated by means of pinions carried by a drive-shaft, which in turn is driven from a suitable source of power, such asa gasolene engine, mounted on the carriage of the press. In such presses, owing to the eccentric mounting of the drive gears, it is necessary that the pinions which drive said gears move toward and from the axis of rotation of said ec centric gears so that they may constantly mesh therewith, and one of the objects of my present invention is to provide improved means for mounting such pinion or pinions so that they may constantly be held in proper relation to the eccentric gear or gears. In such presses, it is also desirable to vary the tension of the belt or belts by which the drive-shaft is driven from the engine, so as to increase the belt tension during the compression stroke, at which time the greatest power must be applied to the eccentric gears, and to reduce-such tension during those parts of the stroke when less power is required, and another object of my present invention is to. provide for automatically securing this variation in the tension ofthe belt. I j

A further object is to provide for accommodating the tensionrregulating devices to Specification of Letters Patent. Fate inter} Sgpt 14, 19111 Application filed December 22,1913 Serial No. 808,194.

associated parts; and Fig. 1 is a plan view of the parts shown in Fig. 3.

, Referring to the drawings, 5 indicates the frame of the press, which may be of "the usual construction, and inthe illustration,

is shown as mounted on wheels 6,. so that it may be transported. '7' indicates the baling chamber, and 8 the plunger, which is in Fig. 1, the arrangement being suchthat as the gears 9 rotate, the plunger 8 is moved back and forth. These parts areall substantially the same as the corresponding parts shown and described in my said pends ing application. 9 I I 13 indicates agasolene or other suitable engine. which is mounted-on the frame 5 on a support 1s movable longitudinally of said frame by means of a crank 15. 16 indicates the crank-shaft of, the engine, and 17 pulleys mounted thereon. 18 indicates fly wheels, also mounted on the crank-shaft16. These parts also are substantially the same as those shown and described in my said application.

19 indicates a drive shaft, which, as shown in Figs. 3 and 4, is mounted in suitable bearlngs. provided in arms 20, pivotally" con nected with the gears 9 at the center thereof, as shown at 21inFig. 3. The arms 20, therefore, extend radially from thecenters of the gears 9, and slightly beyond the peripheries thereof, the arrangement being such that they operate to hold the shaft 19'at such a distance from the peripheries of the gears9 that pinions QZcarried by said shaft always mesh properly with the gears 9, as shown in Fig. 4;.-

23 indicates links, which at one end are connected with a sleeve 24-, mounted 'onthe shaft 19, adjacent to the pinions22, and at the other end are adjustably connected with standards 25 rising from the frame5, as shown-1n Fig. l. The links '23 cooperate with the arms 20 to hold the shaft, 19 in proper operative relation to the gears 9, and 1 as shown in Figs. 1 and 3, they are so arranged as to hold said shaft in a position above said gears and between the pulleys 17 and a vertical plane passing through the axes of said gears 9. It will be seen, there fore, that as the gears 9 rotate, the shaft 19 will-rise and fall, as determined by theeccentricity of said gears, but the pinions 22 will always remain in mesh with said gears, the eccentricity of the latter being automatically. compensated for.

26 indicates pulleys carried by the drive shaft 19, and 27 indicates belts connecting said pulleys with the pulleys 17 on the crankshaft 16. As clearly shown in Fig. 3, the links 23 are connected with the standards 25 at a point lying slightly above'a line connecting the crank-shaft 16 with the drive-shaft 19 when the latter is at its liighest point. The result is that as the driveshaft 1'?" falls, owing to its moving closer to the axis of rotation of the gears 9, said shaft 19 and the pulleys, carried by it will be moved closer to the'crank-shaft 16, owing to the change in the angular position of the links .23, thus reducing the tension on-the belts 27 On the other hand when the driveshaft 17 is moved upwardly, the nearer the links 2 3 approach to coincidence with a line connecting the shaft 19 with the crank-shaft 16, the greater will be the tension upon the belts 27 As the latter movement takes place when the shaft 19v is at its greatest distance from the axis of rotation of the gears 9, which is during the compression stroke, it

will be apparent that during the compression strokethe tension upon the belts 27 will be the greatest, and that after the completion of the compression stroke, at'iwhich time the drive shaft 19 approaches closer to the axis of rotation of the gears 9, the tension upon the belts 27 will be reduced.

In order that the tension governing devices, may beadjust'ed, thelinks 23 are connected with the standards 25 so that the ends shown at the left-hand infthe illustration maybe moved up or down, this beingv preferably accomplished by providing a series of holes 28' in the standards 25'to receive the bent ends of said. links, as shown in Figs. 3 and 4. Obviously, if the ends of the links 23 be placed in the topmostholes 28, ,the other connections remaining the same, the greatest tension upon the belts 27 will be less than where the links are placed in the intermediate holes, or in the lowermost holes. This construction also provides for adapting the apparatus tolengines of different sizes or makes, since the distance from the base ofv the engine to the crank-shaft varies with different engines. 'The standards '25 are preferably mounted as. close to the engine fiv wheel aspossible, so as to give a reasonable length to the links 23, and thereby avoid extreme variation of the belt tension.

It will be understood thatthe drawings illustrate one embodiment of my invention,

. and that it may also be embodied in various other forms. The claims hereinafter made are therefore to be construed accordingly.
